-------------------------------------
Hi,Jark Wu,Thanks for your suggestion. We only support HBase 2.2 in our work.
We add a HBaseRowDataAsyncLookupFunction class extends
AsyncTableFunction<RowData> Support async lookup for HBase connector in the
flink-connector-hbase-2.2 module.
Detailed scheme:
1.Add lookup.isAsync option to check if async mode is enabled.
2.Use HBase Async Client to lookup data
3.We can use guava cache like JdbcRowDataLookupFunction to have a memory cache.
4.If we want to get cache usage, we can also add a hitRate metric.

> Components: Connectors / HBase, Table SQL / Ecosystem
> Reporter: Jark Wu
> Priority: Major

> Currenlty, {{HBaseRowDataLookupFunction}} implements {{TableFunction}} which
> is a sync operation. Would be better to have an {{AsyncTableFunction}}
> implementation which has better performance.
